PORTABLE METAL-PUNCH.

Specification of Letters Patent No. 10,681, dated March 21, 1854.

T0 all whom t may concern:

Be it known that I, SAMUEL MOKENNA, of' the city of Cincinnati, county of Hamilton, and State of Ohio, have invented a new and useful Machine, which I call a portable punch for punching the notches required in the lower flanges of wrought iron rails near their extremities to secure them to the chair on which they are laid to form the railroad-track; and I hereby decla-re that the following is a full, clear, and eXactdescription of its construction and mode of operation, reference being had Vto the anneXed drawings making a. part of this specilication, in which# Figure l represents the side elevation of the punch placed on the rail for thepurpose of operating; Fig. 2, a front elevation, and Fig. 3 a plan of the same, the same letters designating the same parts in all the figures. A is a tongue of wrought iron, orother metal, turning on the -bolt e e, bearing the steel dies or cavities, seen in Figures 1 and 2 defined by dotted lines marked X X, and serving to distribute and transmit the pressure brought upon it by the steel or metal eccentric B turning around the axle marked' j f and maneuvered by the strong wooden lever marked Honly partly shown in the drawing.

C C, are jaws of' wrought iron, or othery suitable metal, embracing the flanges'of the rail co-nnected by the stirrup s which passes under it, and supporting the puncheso, 0, 0, o, which have a suitable shape and projection to make the required notches or holes to be punched.

To operate the machine, raise the end of the rail a few inches above ground, bottom flange upward, place the punch over the end of it as shown in Figs. 1 and 2 shoving it back until the punches are at the gage mark for the holes or notches, then by the lever, revolve the eccentric.

I do not claim the invention of the punches, the dies, or lever and eccentric as a means of applying pressure; but

What I` claim, and wish to` secure by Letters Patent, is-

The arrangement for al portable punch, of

.the tongue connected jaws,'stirrups, punches,

dies, lever and eccentric, as hereinbefore described. l:

SAMUEL MCKENNA.
